The ultra-wealthy are investing in cryogenic freezing, preserving their bodies at ultra-low temperatures with the hope that future science will bring them back to life. Around 500 people have already been cryogenically preserved and another 5,500 people are making plans to do so. But what is it? How does it work?
According to the BBC, the foundation of cryogenics was laid by French biologist Jean Rostand in the 1940s. However, the concept of cryogenic freezing as a path to potential immortality was first proposed by Robert Ettinger in his 1962 book, The Prospect of Immortality. Ettinger, a physics teacher and war veteran, drew inspiration from Rostand’s work and the imaginative worlds of science fiction.
In 1967, James Hiram Bedford, a former psychology professor at the University of California-Berkeley, became the first person to undergo cryonic preservation. Bedford, who passed away from renal cancer in January 1967, remains frozen in time, waiting for science to catch up with humanity’s oldest dream: defeating death.
